Popis: In this paper, effectiveness of freezing process on particle removal efficiency (PRE) for various sizes and polycrystalline silicon line damages was studied by a method which consists of freezing and melting water film on the wafer. It was found that this sequence, freezing and melting process, could remove particles, especially for small-sized particles (e.g. 40-nm particles) with high efficiency, without any damages on 37-nm polycrystalline silicon lines and material loss.
